A CLASS ACTION AGAINST DOW CHEMICAL REGARDING ITS MERGER WITH UNION CARBIDE IS ANNOUNCEDMay 3, 2000

The following was released today by the Law Offices of Curtis V. Trinko, LLP and
Goodkind Labaton Rudoff & Sucharow LLP:

Notice is hereby given that a class action lawsuit was filed in the United States
District Court for the Southern District of New York on behalf of all persons who held the
common stock of Dow Chemical (NYSE: DOW) since August 13, 1999.

The complaint alleges that Dow violated federal securities laws, including Section
13(d) of the Securities Exchange Act of 1934, in an SEC filing on August 13, 1999 that
contained false statements and omissions concerning potential liabilities and dangers of
business disruption to which Dow would be exposed upon its acquisition by merger of Union
Carbide.

Specifically, the complaint alleges that Dow failed to disclose that Union Carbide is
exposed to potential liabilities from its former pesticide plant in Bhopal, India that (i)
released poisonous gas in 1984 that killed thousands and injured half a million people,
and (ii) continues to cause environmental contamination in a densely populated region.

The complaint alleges that Dow failed to disclose that:

(i) Union Carbide is criminally charged in India for the Bhopal Disaster with culpable
homicide and other charges, which expose it to potentially billions of dollars of
liability;

(ii) Union Carbide failed to appear in Indian criminal courts, was proclaimed an
absconder and its assets in India were attached;

(iii) Dow's Indian holdings will likewise be in danger of attachement by Indian courts;

(iv) Dow's plans to expand operations in India will, therefore, be jeopardized; and

(v) Union Carbide remains liable for damages from environmental contamination from its
former Bhopal pesticide plant.

The complaint further alleges that Dow's failure to address these matters has caused:
(i) Dow to understimate the liabilities it stands to assume pursuant to the merger, and
(ii) that Dow made an excessive offer for Union Carbide.
